* Optimize none? and one? relation query methods to use LIMIT and COUNT.Eugene Gilburg2015-02-121-0/+34
| | | | | | | | Use SQL COUNT and LIMIT 1 queries for none? and one? methods if no block or limit is given, instead of loading the entire collection to memory. The any? and many? methods already follow this behavior. [Eugene Gilburg & Rafael Mendonça França]

* Remove Relation#bind_paramsSean Griffin2015-01-271-1/+1
| | | | | | | | `bound_attributes` is now used universally across the board, removing the need for the conversion layer. These changes are mostly mechanical, with the exception of the log subscriber. Additional, we had to implement `hash` on the attribute objects, so they could be used as a key for query caching.
* Use an `Attribute` object to represent a bind valueSean Griffin2015-01-271-3/+2
| | | | | | | | | | | The column is primarily used for type casting, which we're trying to separate from the idea of a column. Since what we really need is the combination of a name, type, and value, let's use the object that we already have to represent that concept, rather than this tuple. No consumers of the bind values have been changed, only the producers (outside of tests which care too much about internals). This is *finally* possible since the bind values are now produced from a reasonable number of lcoations.

* Change `having_values` to use the `WhereClause` classSean Griffin2015-01-261-2/+18
| | | | | | | | | | | | | | | | | | | | | | | | | | | This fixed an issue where `having` can only be called after the last call to `where`, because it messes with the same `bind_values` array. With this change, the two can be called as many times as needed, in any order, and the final query will be correct. However, once something assigns `bind_values`, that stops. This is because we have to move all of the bind values from the having clause over to the where clause since we can't differentiate the two, and assignment was likely in the form of: `relation.bind_values += other.bind_values` This will go away once we remove all places that are assigning `bind_values`, which is next on the list. While this fixes a bug that was present in at least 4.2 (more likely present going back as far as 3.0, becoming more likely in 4.1 and later as we switched to prepared statements in more cases), I don't think this can be easily backported. The internal changes to `Relation` are non-trivial, anything that involves modifying the `bind_values` array would need to change, and I'm not confident that we have sufficient test coverage of all of those locations (when `having` was called with a hash that could generate bind values).

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | callbacks and validations - Right now, there is no method to update multiple records with validations and callbacks. - Changed the behavior of existing `update` method so that when `id` attribute is not given and the method is called on an `Relation` object, it will execute update for every record of the `Relation` and will run validations and callbacks for every record. - Added test case for validating that the callbacks run when `update` is called on a `Relation`. - Changed test_create_columns_not_equal_attributes test from persistence_test to include author_name column on topics table as it it used in before_update callback. - This change introduces performance issues when a large number of records are to be updated because it runs UPDATE query for every record of the result. The `update_all` method can be used in that case if callbacks are not required because it will only run single UPDATE for all the records.
* | Remove `klass` and `arel_table` as a dependency of `PredicateBuilder`Sean Griffin2014-12-261-1/+2
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This class cares far too much about the internals of other parts of Active Record. This is an attempt to break out a meaningful object which represents the needs of the predicate builder. I'm not fully satisfied with the name, but the general concept is an object which represents a table, the associations to/from that table, and the types associated with it. Many of these exist at the `ActiveRecord::Base` class level, not as properties of the table itself, hence the need for another object. Currently it provides these by holding a reference to the class, but that will likely change in the future. This allows the predicate builder to remain wholy concerned with building predicates. /cc @mrgilman
* | Inject the `PredicateBuilder` into the `Relation` instanceSean Griffin2014-12-261-1/+2
|/ | | | | | | Construction of relations can be a hotspot, we don't want to create one of these in the constructor. This also allows us to do more expensive things in the predicate builder's constructor, since it's created once per AR::Base subclass

| | | | | | | | | | | * Also duplicated find_by tests from relations_test.rb to finder_test.rb now that we have a completely different implementation on the class (in core.rb with AST caching stuff). * Also removed a (failing) test that used mocks. Now that we have tests for the behavior, there's no point having another test that tests the implementation (that it delegates). Further, what the test was implying is nolonger true with the current implementation, because Class.find_by is a real method now.

* Add missing test case for quoting behaviorSean Griffin2014-05-261-0/+7
| | | | | | | | It appears that the only time that `quote` is called with a column, but without first calling `type_cast` is when where is called with an array. My previous pull request broke this behavior, without failing tests. This adds a test for the only case I can think of that exercises the `if column.type == :integer` branch of `quote` effectively.

| * The Association Relation should use `empty?` and `size` from Relation.Lauro Caetano2014-04-141-0/+11
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | 968c581ea34b5236af14805e6a77913b1cb36238 have introduced this bug #14744 on Association Relation when the method `empty?` or `size` was called. Example: # Given an author that does have 3 posts, but none of them with the # title 'Some Title' Author.last.posts.where(title: 'Some Title').size # => 3 It was occurring, because the Association Relation had implemented these methods based on `@association`, this way giving wrong results. To fix it, was necessary to remove the methods `empty?` and `size` from Association Relation. It just have to use these methods from Relation. Example: # Given an author that does have 3 posts, but none of them with the # title 'Some Title' Author.last.posts.where(title: 'Some Title').size # => 0 # Now it will return the correct value. Fixes #14744.

| * Build the reverse_order on its proper method.Lauro Caetano2014-04-071-0/+12
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The reverse_order method was using a flag to control if the order should be reversed or not. Instead of using this variable just build the reverse order inside its proper method. This implementation was leading to an unexpected behavior when using reverse_order and then applying reorder(nil). Example: Before Post.order(:name).reverse_order.reorder(nil) # => SELECT "posts".* FROM "posts" ORDER BY "posts"."id" DESC After Post.order(:name).reverse_order.reorder(nil) # => SELECT "posts".* FROM "posts"
